There’s currently a handful of airlines who have been using the system at select airports on outbound flights. One of the biggest benefits of the system is that it speeds up the boarding process. For example, Delta’s initial trials showed that the facial recognition option saves up to nine minutes per flight and Lufthansa’s initial trials showed they could board approximately 350 passengers onto an A380 in about 20 minutes.

Whether you have a long day of travel ahead or not, anywhere you can save time on the journey is always appreciated.
